MUC5B and Idiopathic Pulmonary Fibrosis.

ABSTRACT: Idiopathic pulmonary fibrosis (IPF), a fatal disease that is a result of complex interactions between genetics and the environment, has limited treatment options. We have identified the MUC5B promoter polymorphism and other common genetic variants that in aggregate explain roughly one-third of disease risk. The MUC5B promoter polymorphism is the strongest and the most replicated genetic risk factor for IPF, appears to be protective and predictive in this disease, and is likely involved in disease pathogenesis through an increase in MUC5B expression in terminal bronchi and honeycombed cysts. Expression of MUC5B is also highly correlated with expression of cilium genes in IPF lung. Our work suggests that mucociliary dysfunction in the distal airway may play a role in the development of progr
